SUMMARY:Pathways to Detecting and Characterizing Rocky Habitable Plane
 ts\, Astronomy Colloquium\, Gudmundur Stefansson\, Princeton Universit
 y
DESCRIPTION:One of the foremost goals of exoplanet science is the deta
 iled characterization of terrestrial planets that potentially could ha
 rbor life. I will discuss near-term projects and instruments that are 
 allowing for rapid progress on the detection and characterization of s
 mall planets. (1) Beam-shaping optical diffusers allow us to approach 
 the precision of space-based photometry with ground-based telescopes\,
  thereby enhancing our ability to detect and study terrestrial planets
 . (2) Improvements in Doppler spectrographs—including HPF and NEIDâ€
 ”will expand our knowledge of the compositions\, architectures\, and a
 tmospheres of small planets. (3) The ongoing 5-year HPF survey will de
 tect terrestrial planets in the habitable-zones around nearby mid-to-l
 ate M dwarfs\, some of the most favorable systems for direct imaging w
 ith future flagship missions. (4) Synergy between M dwarf planet surve
 ys and low-frequency radio surveys offer the possibility of opening th
 e door to a new field within exoplanet science: star-planet magnetic i
 nteractions\, which may affect planetary habitability.<br>
